Title: An arrangement for practising firing by means of compressed air from machine guns and other light guns
IPC: F41B11/55
Filed: 1936-11-24
Abstract: 485,205. Adapting automatic guns for practice fire. OESTERREICHISCHE AGA. WERKE AKT. - GES. Nov. 24, 1936, No. 32118. Convention date, Dec. 4, 1935. [Classes 92 (ii) and 119] Relates to means for adapting existing machine and like guns for practice fire with pneumatically propelled pellets, of the kind in which a piston 6 moving in a cylinder 3 is operated by compressed air against the action of a run-out spring 8. According to the invention, the piston opens near the end of its forward movement a valve 14 to admit air to the cylinder through ports 21 to throw the piston back against the compressed run-out spring to simulate recoil. The attachment shown comprises a member 1, the forward part of which forms the practice barrel 2, the rear part forming the cylinder 3 for the piston 6, the rod 5 of which bears against the run-out spring 8. The piston carries a hollow rod 18 which pushes pellets from a magazine 19 and forms a duct for the air under pressure which effects their discharge. The pellet magazine 19 and the air admission valve 14 are accommodated in the existing magazine casing of the gun. To start the gun, the piston is released by a trigger and moves forward to close a passage 23 by impact against a buffer 16 and valve 15. At the same time, a sleeve 12 carrying a tapered grooved member 10 is pushed forward to open the inlet valve 14, the valvo being retained open by the groove which engages the stem of the valve. The entering air forces the piston rearwards until the sleeve 12 is returned to close the inlet valve and open passage 23 and duct 24 whereby the air passes to the other side of the piston to balance the pressure and cause the return of the piston under the action of the run-out spring. The air passes to the interior of the discharge rod 18 as soon as passages 25 in the piston rod align with the duct 24. After discharge of a pellet, the piston again actuates the members 15, 10 and the operations are repeated.

Title: Improvements relating to remote control devices for radio receivers
IPC: H03J1/18
Filed: 1930-10-25
Abstract: 354,124. Wireless receiving apparatus. KOLSTER-BRANDES, Ltd., Cray Works, Sidcup, Kent.-(Kolster Radio Corporation ; 200, Mount Pleasant Avenue, Newark, New Jersey, U.S.A.) Oct. 25, 1930, No. 32121. [A Specification was laid open to inspection under 'Sect. 91 of the Acts, Oct. 27, 1930.] [Class 40 (v).] In a remote control device for tuning a radio receiver, the motor for driving the tuning-spindle and a potentiometer device for indicating the setting at the control point, are housed in a casing so as to be readily attachable to an existing radio set. The tuning-knob or shaft 18 is operated through reducing-gear by an electric motor 14 housed in a box 3 placed adjacent the set 1. The motor is controlled by pushbuttons 8, 9 at the remote control point, the buttons serving for forward and reverse movement respectively. A potentiometer arm 22 on the final drive spindle 27 moves over a stationary resistance 21, which is connected across a suitable source such as the filament battery of the set, or the H.T. supply. A voltmeter 4 at the control point is connected to the movable arm and to one side of the battery and thus indicates the tuning position. Volume of reproduction is regulated from the control point by a rheostat operated by a knob 10 and arranged to vary the filament current of the valves. The various wires connecting the control point to the set are formed into a cable 5 which may be stored on a spring drum.

Title: Improvements in devices for feeding liquid fuel to carburetters of internal-combustion engines
IPC: F02M37/02
Filed: 1920-11-13
Abstract: 161,554. Thivolle, L. April 10, 1920, [Convention date]. Vacuum apparatus.-Relates to devices for raising liquid fuel from a low-level tank to a vessel supplying the carburettor, and for maintaining the liquid level in the vessel constant notwithstanding variations in the density of the fuel. In the device shown in Figs. 1 and 3, the vessel 26 from which the carburettor is fed has an inner cylindrical part of two diameters in which moves a bell-shaped piston also of two diameters. The smaller end of the piston is subject to the action of suction through a pipe 5, and has a central opening 16 through which the suction effect passes to the interior of the piston under the control of a float-actuated valve 24. With the parts in the positions shown in Fig. 1, the reduced pressure in the piston due to the starting of the engine allows fuel to rise through the pipe 9 past the non-return valve 10. The liquid raises the float 19 and when at the desired level the valve 24 is closed. The suction effect in the interior of the piston is thus removed and the piston rises from the shoulder 21 on which it rested, admitting the liquid to the annular groove 21, from which it flows through a nozzle 13 provided with a non- return valve 14. Air rises through the fuel from an opening 25 in the nozzle. The level in the vessel 26 cannot rise above the level of the seat of the ball 14. To facilitate the starting of the engine, a spring valve b is opened by pulling a line h to allow fuel to pass through pipes i, 5. In one modification only the smaller part of the piston moves in a cylinder, and in another neither part fits a cylinder and the upper part is connected to a diaphragm subject to the suction.

Abstract: 673,713. Liquid-fuel burners. MESCHINO, R. G. Dec. 15, 1949 [Dec. 30, 1948], No. '32182/49. Class 75(i) In a liquid fuel burner in which fuel under pressure is passed through ports leading non-radially to an open passageway connecting nozzle orifices at opposite ends thereof, the ports enter the passageway in a like torque-inducing direction so as to produce a swirling, annular body of fuel having an air core extending through the nozzle orifices. Liquid fuel supplied through a conduit 11 to an annular chamber 35 and by a duct 19 therefrom to an annular chamber 35<SP>1</SP> passes through ports 33, 33<SP>1</SP> leading tangentially from the chambers 35, 35<SP>1</SP> into a concentric passageway 36, 36<SP>1</SP> having nozzles 13, 14 at opposite ends to form a swirling body of liquid with an air core 39 extending through the nozzles 13, 14, thus ensuring stability by the absence of any drag at an end wall. The burner shown is a spill-type burner in which the swirl chambers 31, 31<SP>1</SP>, are of greater diameter 'than the passageway 36, 36<SP>1</SP> with the spill returned to the source through a pipe 12.. In a duplex type arrangement, Fig. 6 (not shown), fuel is supplied at constant pressure through one pipe 42 and, at a variable pressure, through a second pipe 43. The fuel issuing from nozzles 13, 14 may be apportioned by a suitable choice of their outlet orifice diameters.

A contact printing apparatus comprises a rotatable glass cylinder 1 having an internal lamp 2, and a system of belts 4 which carry the original and copy sheets round the cylinder while the exposure is made. Let into the surface of the cylinder is a clamping device 11 (also having ejector pins 12) by means of which the leading edge of the original 0 may be attached to the cylinder. This is fed in between guide plates 13, 14 by a roller 17, which contacts the sheet simultaneously with the removal of a stop 16. Similarly the copy sheet K is fed in between guides 18, 19. The driving roller 8 for the belts 4 is geared to a roller 28 which drives the cylinder 1. The arrangement is such that the belts move faster than the cylinder, preferably by 0. 5 to 3%. It is stated that this prevents the original from being detached so readily from the clamping device when it is sent round again and again for repeated copies.

Title: Improvements in or relating to rubber articles and method of making the same
IPC: B29C37/00
Filed: 1936-11-28
Abstract: Rubber articles, e.g. bathing caps, or sheet rubber are produced by depositing, e.g. by spraying, spreading or dipping, and coagulating a thin film of latex on a deposition surface having a raised or depressed pattern, and spraying on latex under such conditions that particles of latex are deposited and coagulated to form a pebbled or spongy surface, without running together, or filling in the depressions.  The spongy effect is produced by using a coarse spray or more viscous latex, or by increasing the speed of coagulation of the spray, as by heating the deposition surface, spraying through heated gas or air, or by alternately spraying with coagulant.
